SPECIFICATION forming part of Letters Patent No. 439,921, dated November 4, 1890. Application filed May 7,1888. Serial No. 273,103. (No model.)

To all whom it may concern.-

Beit known that I, JOSEPH THOMPSON Wrn LIAMS, a citizen of the United States, residing at Easton, in the county of Northampton, State of Pennsylvania, have invented a new and useful Improvement in Anchors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of improvements in anchors, as follows: The novel construction of the points of the flukes, and, next, the combination of parts, as will be hereinafter fully described, and pointed out in the claims.

Figure 1 represents a perspective view of a portion of an anchor embodying my invention, the parts being separated. Fig. 2 represents a section thereof on line a; 00, Fig. 1.

Similar letters of reference indicate corresponding parts in the two figures.

Referring to the drawings, A designates the shank of an anchor, and B the flukes; O, the yoke, and D the pivoted bolt thereof, said bolt passing through the sides of the yoke and the bifurcated crown E of the shank. The said yoke is open, thereby leaving a space between the same and the crown of the shank, whereby dirt, sand, and other obstacles may readily pass through said yoke, thus avoiding clogging or fouling the anchor about the pivotal portion of the same. The front faces of the cross-pieces of the yoke C are concave or scoop-shaped, leaving salient lips G, which are caused to engage with the bed of the water, as will be more fully set forth. The edges of the said lips and the concave or scoopshaped faces of the yoke are in front of a line drawn through the pivot of the crown and at right angles with the palms of the flukes of the anchor, whereby when the anchor is normally resting on the bed the lower lip is in position to catch easily on said bed, being in the rear of the pivotal point of the crown, and the upper cross-pieces of the yoke are in front of said pivotal point and adapted to abut against the shank as a stop, the upper concave face receiving the impact of the water as the anchor is dragged, and thus forcing the lower lip against the bed, so as to take hold of the same. The back and corners of the yoke are rounded, so as to cause the anchor to roll and cant or right itself should either of said parts first strike the bed when the anchor is lowered. The flukes project outwardly from the sides of the yoke in a right-angular direction therefrom, so that they are prevented from spreading.

The flukes B are spear-shapedand Hat and sharpened at the points, as at B, the flat side's extending at a right angle to the plane of the palm of the flukes and parallel with the sides of the shank, the advantage of this form of construction being that the flukes most readily penetrate the bed of the water.

It will be seen that the objects of either lip G or the scoop-shaped yoke C are twofold. First, it acts as a fulcrum and causes the anchor to catch quickly and more reliably, as it and the points of the flukes and fluke-arms work in concert of resistance with the bottom of the water, and as the anchor is drawn forward when in use it is thus caused to penetrate and take hold of the bottom and assume a vertical position for giving firm and reliable resistance to the cable. Second, this scoopshaped yoke acts as a fulcrum to break loose the strong hold of the anchor. In this way the anchor is forced very tight and wedged under the rocks, and when the slack of cable is taken up until the vessel is almost perpendicular over the anchor in the water, ready for breaking its hold, a very slight wind will give motion to the water sufficient to cause the vessel to slightly jerk and slack the cable, whereby the said fulcrum would cause the anchor-flukes to back out from under any hold it may thus have in the bottom, instead of breaking off the arm of the fluke, as often occurs in other anchors. This scoop-shaped yoke also prevents fouling of the cable, as there are no projecting points thereon liable to foul or catch the cable.

The spear-shaped flukes with points thereof made fiat and sharp, the opposite way to all other anchors, and parallel with the shank of the anchor, as shown, is another feature of advantange for quickly and surely catching and penetrating the bottom.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An anchor having the point of its flukes flat and sharpened forming an edge at rightangles to the plane of the palms of the flukes, 3. An anchor having a yoke which is piv- 1c the flat sides extending parallel with the oted to the shank thereof and provided with shank, substantially as and for the purpose salient lips and concave faces, said yoke and set forth. the crown of said shank being of open form',

2. An anchor having a shank with a bifursubstantially as described. cated crown and flukes which extend at a JOSEPH THOMPSON WILLIAMS. right angle from the sides of said yoke, said \Vitnesses: parts being combined substantially as de- G. K. WILLIAMS, scribed. CHARLES P. AYERS.
